Individuals can differ in the degree of closeness they desire in their romantic relationships: Some people may perceive their current level of closeness as just right, whereas others may feel not close enough or too close to their partners (referred to as negative and positive closeness discrepancy, respectively). This study (N = 1,177 individuals from 748 couples) examined the implications of closeness discrepancies for subjective relationship quality (SRQ) using dyadic response surface analysis. The analyses found evidence for linear, but not broad, closeness discrepancy effects: SRQ was lower for individuals reporting more negative closeness discrepancies and, independent of this actor effect, for individuals with partners who reported more negative closeness discrepancies. These results suggest that low levels of closeness paired with a strong desire for closeness can impair both partners’ relational well-being.
